7.2 List of model data for download (newer models here)

Table 3 lists the spherical harmonic expansion model-files we calculated based on the original tomography models (see sec. 2); original model ftp-locations are given in Table 2. To download the gzipped spherical harmonic coefficients in the format as described in sec. 7.1, click on ``download here'' in Table 3. Models are sorted by complexity in terms of the compressed information content of our spherical harmonic expansions. We note that rum is upper mantle only.
